This invention relates to that type of duplicator in rWhich a negative or reversed impression of the matter to be copied is 1mpressed upon a gelatinous duplicating surface or the like and positive ,impressions taken therefrom by bringing sheets of paper or the like successively into contact therewith. Y

The invention consists in the novel construction, arrangement and combination of various devices, elements and parts, as set forth in the claims hereof, one embodiment of the same being illustrated in the aecompanying drawings and described in this specification.

In ythe accompanying drawings,

Fig. 1 is a side view of a duplicator embodying our invention;

Fig. 2 is a longitudinal vertical section;

Fig. 8 is a plan View;

Fig. 4 is an end view; anc

Fig. 5 is a perspective view of the stick or'spindle upon n'Which the duplicator film may be Wound.

In carrying our invention into .effect inl the embodiment thereof Which` We have selected for description `in this specification and Villustration in the accompanying dravvings,v weprovidea duplicator, the frame of which may be of any suitable type, such as for instance comprising frame members 12, in which are journaled rollers 13 upon Which an adhesive duplicating film 14 is adapted to be Wound. The `film 14 passes upivardandover a bed 16 securedbetiveenthe members 12, rollers 15 adjacent the `ends of the bed being adapted to prevent the yfilm fromscraping against the said ends when the rollers13 are rotated.

One of the rollers 13 forming part of our invention is shown in perspective in Fig. 5.

It comprises a body portion, around which the film is Wound, and a lug 2O at each end adapted to constitute a chuck-engaging journal.

rIhe rollers are operatively connected With l the frame as follows: Near eachend of the side frame l2 on the leftv of the machine is v provided a. shaft 10 (see Fig. a) rotatably mounted insaid frame, the innerends of which are provided vvith vgrooves adapted to 'receive the lugs 2O of the rollers. The inner ends of the shafts 10 project laterally frame at 69 (see Fig. 2).

inside VAof the inner vvall of the side frame and are surrounded `by annular Walls 70 (see F 1g. et). To these shafts are lsecured operating cranks 17 and ratchets 18, and pivoted onthe frame are paivls 19.

On the other of said side frames are Vprovided devices for removably .engaging the other ends of the rollersv 13. VThese devices consist of rotatable shafts 65 ournaled in the side frame 12 on the right of the. machine. These shaftsV 65 are provided With grooves analogous to those in theshafts 10, and which are also adapted to receive the lugs 2O of the rollers. vided at their outer ends.. with counter- Weights 66 soadjusted ythat When vthe shaft and counterweight lie free, that is,v disengaged from the roller 13, the groovev Will lie approximately in a horizontal position.

The inner ends of the shafts 65 are sur` rounded, except for small openingstovvards the ends of the machine,by broken annular Walls 67, the open spaces left 'in these Walls The shafts 65 are pro-v being normally closed by @double-angled levers 68 pivoted to the inside of the side A spring168 lis providedwvhich tendsv to Vhold each lever/68 in' its raised position, as shown in F ig.f2.

In order toplace the roller 13 in the ma.

chine, the lug at one endv is inserted vin the groove in the inner end'of theshaft 10, and

the same is thereupon held. in position 'by the annular Wall 70. The lever '68 on the other side ofthe machine is then depressed, y

which permits the lugQO on the other end of the roller to be inserted vin the groove in the innerend of the shaft 65. VThe lever 68 is then raised andthe roller will be then held securely in positionand yet perfectly free to rotate.

yIt is obvious that by meansofthe construction above described either end of thel roller may be journalled in either sidejof the machine andthat accordingly a pair Iof l such rollers,bearing a duplicating band,may

be takenfrom the machine, the rollers reversed end forl end and the bandzturned in the direction the reverse of its. former direction, and they rollers again inserted in the machine, butv at opposite endsfrom those in which they were previously,jOnrnaled.'

y In connection with the lower part vof the structure above described, We provide a los paper-support or table member having sides 21, a front end 22, and a bottom 23 covering the greater part of the area, butrhaving an open portion at one end. yThis table is provided at each side near the rear end with downwardly .extending lugs 2st, the 'lower y ends of said lugs being rigidlyy secured to a rod 25 journaled in the side members 12, spring`26 is provided, which tends to norends of sheets otpaper laid upon said table,

and similar stops 31 adapted to bear against the sides of such sheets. Alliot these stops are adjustable, whereby the table is adapted to receive sheets of paper ot various diiierentY sizes. i

Near the front end of the table and projecting over the open space let-t in the same,

is a bar 35. This bar is supported at its ends by'resilient arms 36, secured to the floor ot thetable.vr

Located on the right hand side of the machine (best shown in Fig. 3)Ysecu'red in brackets is a rod 51. `Slidably mounted kon this rod is aframe 52 havingA alateral extension 53 in which isl journaled a roller- Y 54. A handle 55 is provided in the extension `53 to facilitate the manipulation thereof.

This frame, and roller whenin operative positionvlie horizontally as shown in Figs. 1, 3 and ,4, but may be swung out ot the way into al vertical position as shown kin part in F ig. 2. The roller 54 is adapted to roll over thebedl ot the machine during the greater lpart of its course, but at the forward end of its path the ends of the roller run upon slightly elevated tracks 16 (see Fig. 1).

In the rear endet the fra-me 52 is a socket, f

the upper wall otwhich is designatedV 61 (see Fig. 1). VThissocket is adapted to engage with a pin 62 on the side 21 of the paper-table, when the frame is in the'position shown in full lines in Fig. 1 and there Vby hold the paper-table in its lowered posi- :tion against the action of the spring 2G when the machine isnotin use." Whenit -is desired to operate the paper-table, the frame 52'and connected parts are drawn backward l into the position shown in dotted lines Ain Y Fig. l, thus releasing the forward end of. -60

the paperftable and allowing itfto spring upward into the position shown in dotted lines in Fig. 1. r 1

The operationV of ourwinvention is as follows: Upon the table-is placed, face downward, a sheet ofpaper bearing the matter upon which it is desiredto copy the matter transferred trom the original to the duplicating medium, so that one end of each of saidtsheets ot paper shall rest against the lower end 22 ot the table and the side edges of said sheets shall rest against the stops 31,

and the other end of said sheets shall restV againstthe stop 30, it being understood that the stops 30 and 31 are adjusted so as to permit the sheets ot paper to easily liebetween them. It it is desired to use paper of lthe same size. as the table, the adjustable stops 30 and 31 may ot course be removed. i It will be understood that the ends of the sheets of paper lie over the opening inthe floor ofthe table member, and that after the paper is placed in position the barb()v is swung into position over the ends of the sheets of paper. rihe original and theblank sheets ot paper being thus in place upon the table, the-pile of paper may if desired be steadied by placing the hand upon the same, although ordinarily thiswill not be necessary.` It isto be understood that the table is normallyin its lowered'position as shownin `Fig. 1. The rbarP is then depressed, the effect of .this being-to bring a portion ot the lowest sheet of ypaper in the pile, thatis, in this case, the

original matter to be duplicated,into contact with the `adhesive duplicating mediumv to which it will adhere.

The table being then 1 `swung upward, this sheetot paper will be dragged out from under the pile.V The table being thenmaintained by the spring 26 ina raised positionpressurezmay bev applied to thev sheet of paperthen on the duplicating medium, which is vdone bypassing the roller. 54 backward over the paper, the same being guided by the rod 51.- VWhen the roller 54: is moved forward again,-.into the position s hown in Fig. 1, (it then resting upon the elevated trackways 46) the sheet of paper containing the original matter*Y is then stripped ott, the table caused to assume its vlowered position, and the operation repeated with the blank sheets ot paper :until as many copies as are desired have been made, whereupon a new portion of the duplicating medium may be brought into play,-so that when desired a new impression may be transferred theretov and copies made'fromthe new impression in the manner described. In F ig. 1 of. the drawings 60 represents Va sheet of paper which has been placed upon .the paper table, and the end of. which'thas been depressed so thatl t-has yadhered to theduplicating band v14. The drawing shows the position of the paper just before the table be' gins its upward swing. "It will be clear from an'examination of this Fig'. y1 that as the table rises up, the sheet of paper 60 will be drawn off from the table, and out from underneath any other sheets of paper which may be piled thereupon, and that when the table has finally risenv into the position shown in dotted lines in Fig. 1, the sheet of paper Will lie fiat upon the duplicating band 14, ready to be passed over by the roller 54.

We do not limit ourselves to the particular constructionhereinabove described, as it is obvious that various modifications of the same may be made Without departing from the spiritand scope of the invention.

The advantages of the invention Will be obvious from What has been above said with regard to its construction and operation.

Having thus described our invention, What We claim as new and desire to Secure by Letters Patent is as follows:

1. The combination with a pair of frames and a spindle provided at each end with a chuck-engaging lug, of means adapted to journal said spindle in said frames, comprising a shaft rotatably mounted in each frame provided With a socket adapted to receive a lug of said spindle, and retaining means on one of said frames adapted to secure an end of said spindle in said journal, comprising a broken annular Wall and a lever pivotally attached to said frame adapted When in one position to avoid the break in said wall and to allow the end of a spindle to be inserted in or removed from the adjacent rotatably mounted shaft, and When in another position to close the break in said Wall and hold the end of the spindle therein.

2. The combination with a pair of frames' and a spindle provided at each end. with .a chuck-engaging lug, of means adapted to journal said spindle in said frames, comprising a shaft rotatably mounted in each frame provided ywith a socket adapted to receive a lug of said spindle, and retaining means on one of said frames adapted to secure an end of said spindle in said journal, comprising a broken annular Wall and a lever pivotally 'attached to said frame adapted when in one position to avoid the break in said Wall and signed our names the said DANHEISER and BALDAUF this 7th day of March, 1924, and said FEOHER this 11th day of April, 1924.-
